Consider the environmental design factors that impact storage capacity and performance before you deploy PowerStore. Careful planning ensures that new or expanded storage is sized correctly for the Hyper-V environment. When you deploy PowerStore to support an existing Hyper-V workload, you might already understand the required performance metrics such as storage capacity, bandwidth, and IOPS. If the environment is new, determine the performance requirements so you can correctly size the storage, the storage fabric, and the workload hosts.
You can avoid many short-term and long-term problems when the storage part of the solution provides the right capacity and performance now and in the future. Scalability is a key design consideration.
Work with your Dell Technologies representative to complete a performance evaluation if you have questions about how to correctly size a PowerStore storage solution for your environment and workload.
Total disk storage capacity does not guarantee adequate disk performance. If you install a few large-capacity disks in a storage appliance, capacity needs might be satisfied, but the configuration might not support a high-IOPS workload.
Administrators must plan for IOPS, bandwidth, and capacity to properly size PowerStore for Hyper-V or any other workload.
To optimize performance, administrators identify and mitigate design limitations that cause bottlenecks. A bottleneck negatively impacts performance or functionality under load when a capacity threshold is exceeded with the overall design. Design a balanced configuration end-to-end to optimize a workload so it performs at or near peak efficiency. The following design elements are potential bottlenecks:
